Experimental design and workflow. (A) Preparing decidual tissues for single cell analysis on the CyTOF platform. Our study included tissues from 16 term laboring, 12 term non-laboring, 11 preterm laboring, and 14 preterm non-laboring pregnancies (see Table 1). See Supplementary Methods for antibody staining with 32-antibody panel and CyTOF analyses. (B) After data processing and QC, the cells were first divided into CD45+ (immune) and CD45- (non-immune) pools, then characterized using two additional filters for hierarchical SNE analysis. (C) The first filter identified six immune cell types and six non-immune cell populations by 14 and 11 markers, respectively. (D) The second filter identified 10 T cell subsets, five macrophage/monocyte subsets, and two granulocyte subsets. L laboring, NL non-laboring. DCs Dendritic cells, DSC Decidual stromal cell, EVT extravillous trophoblast. Undefined: No cell-surface markers to identify the cell type.
